This invention relates' to anew and improved hydraulic press, designedmore especially for baling purposes; and it consists of a plurality ofhydraulic rains arranged in such a manner with certain detail parts andwith the plateau of the pressthat the rams are made to operateconsecutively upon or againstthe pla-teau, and a packing and compressmechanism combined in one and the same press.

' A represents the framing of the press, and B the press box. i' Theseparts may be constructed in any proper manner to insure strength anddurability. C represents an upright cylinder secured in the lower partof the framing A. This cylinder is of cast iron, closed at its bottom,'and has itted within it a cylinder, D, which is allowed to rise andfall freely, and constitutes what term a compress ram, (see moreparticularly figs. 10 and Il.) Within the cylinder D thereiis a rodE,which I term a packingram, the rod or ram E being allowed to rise andfall freely within D. The lower end of the cylinder or compress ram D isclosed, and allowed to work waterftight in the cylinder C by means ofapacking, F, secured in position by a ring, G, which lis screwed intothe lever end of D, the packing F being clamped between a shoulder, a,on the ring and the lower end of the rain D, as shown in fig. I0. 'H isa \\'ater-supply pipe which passes up through the bottom of the cylinderC, and through the ring G in the bot-toni of the compress ram D., andthe leakage of water aroundthe pipe H and 'through the ring is preventedby a packing, I, which is fitted around the upper end of the pipe Hwithin a i recess, b, in the upper surface of the ring G, and secured orclamped in position by a ring, J, screwed into the recess I of the ringG, as` shown clearly in iig. 10, K is a` water-supplypipc whichcommunicates with the lower part of the cylinder C, as shown clearly'infig. l0. The lower end of thc ram E has a nut, L, screwed t upon it,with a recess, c, in its under side to receive a nut, M, between ashoulder, d, on which and the lower end ot nut L a packing, N, issecured or clamped by screwing up uut M. The upper cnd of the nut Labuts against a collar, c, on the rod or rain E, which collar serves asa stop, as will be hereinafter described. A modiication of this packingand stop is shown in lig. 11, NX being the packing, L the nut, which isscrewed directly into the lower end of the rod or ram E, and() a ring,which is fitted on an external screw-thread on the lower end ol' theram, the ring O serving as a stop in lieu of collar c. P is the plateauof the press, which is litted and works in thc press box B. The upperend of the rod or ram E bears against the under side of the plateau I),and it will be seen that when water is forced through the pipe II intothe lower part of the compress rain l) the water will act against theram E, which I term the packing ram, as previously alluded to, and theplateau P will be raised until the stop c or O comes in Contact with anut, Q, in the head of the compress ram, at which time the compress ramD is made to rise by Vwater entering the lower end of the cylinder Cthrough pipe K and acting against the bottom of D. The two supply pipesH K are connected at their upper parts by a pipe, R, (see fig. 2,) thewater being forced into pipe R by a pump as usual. The pipeRcommunicates with the pipe Kjust above the valve S, the stern f of whichpasses up through a fixed plate, g, on the framing A, and through avcross-head, T, the arms h h of which incline downward, as shown in figs.2 and 12. Between the cross-head T andthe fixed plate g there areinterposed two sliding wedges, U U, in which the outer ends of' levers VV are fitted, said levers V having their fulcra in the plate g, andtheir inner ends made or formed with recesses t L, as shown in fig. 9,to receive the ends of levers W W, which are attached to the upper endor head of the ram D, said head having two notches or recesses t'z'madein it,.s hown in tig. 14, the use of which will be presently explained.At the inner edge of the fixed plate g there are vertical projections, jj, whiclrserve as rests for what I term litters, X X. These lifters areattached to the under side of' the plateau P by hinges orjoints, c t, asshown in figs. 1, 2, and 5, and in the lower end of each lifter there isfitted an elastic or yielding pawl, Y, shown clearly 'in fig. 1, saidpawls having their under surfaces inclined or bevelled'so that they maybe readily forced upon inclined surfaces Z l on the compress-ram head D,and be made to catch into the recesses t'imade in said surfaces. To theplateau P, at about the centre ot' one side of the same, there isattached a pendent wedge, Z, shown clearly in figs. 1 and 2. On theupper part of the stem f of the valve S there is a spring, f, which hasa tendency to keep said valve closed. In the outer side or cach lifter,X, near its upper end, there is connected by a hinge or joint, m, alever, Y. These levers Y Y have their fulcra n. in metal straps Z Z,which are attached to pendent arms A A secured Ito the'ends of theplateau P, said arms working in contact with thc sides of the press box,and braced by bars o o, as shown ings. 1 and 2. Between the levers Y andthe pendent arms A', to which they are attached, there are placedsprings B. These springs are ttcd on rods 'p which pass through plates qg, arranged so that they may Slide or expand and contract, the platesbeing ofdL-f'orm and connected by abolt r which passes through oblongslots s, (see fig-f3.) These plates q are fitted in vertical groovesmade in the levers and pendent arms A, and to thc bolts r cords u areattached, said cords extending down through the base of the framing ofthe press, and having knobs or weights e attached to them. In thelowerpart of the framing of the press, and about on a level with the top ofcylinder C, there are inserted cross-bars w w, which serve as stops.These stops are in line with the plates g g and springs B, and their usewill be shown in the operation ofthe several parts. At the upper part ofthe press box B there are two doors C C hinged at one end. These doorsare provided with longitudinal battons a which extend beyond thedisengaged ends ot' the doors, and when the doors are closed extendbeyond the Posts b of thc framing, so that a elampframc D may be fittedthereon. This clamp frame is of rectangular form, and constructed offour bars e e c c framed together, the upper and lower horizontal bars cextending beyond one of the side-bars e, and having a vertical bar dfitted on them, the ends of the bars c having tenons made on them to fitin mortiscs in the bar d. To the vertical bar c, which is near thetenons on the ends of the bars c, two metal straps or loops e e areattached, the lower strap being a trifle longer`- than the upper one.The bar d passes through the loops e e', and is retained in position byguide-plates f attached to the sides of CZ over the loops c, (see figs.4 and 7.) E is a key or wedge, which is fitted in the loops e e, andwhen driven up in said loops serves to clamp the two doors C C in aclosed state. The clamp frame D is fitted in guides F, which admit of itbeing adjustedon and off from the ends of the battons a with facility,

and alwaysretain said frame in proper position. On the upper partof thepress box B there is a. 4sliding top or head-plate, G, which works onways or guides g g', which admit of it being readily moved or adjustedover and otf from the top of the press box.

The operation ofthe press, so far as the action of the water upon thetwo rams D E is concerned, has been previously Yalluded to in a brief`manner simply to define or 'render clear the construction of the rams.vI will now proceed to describe the operation throughout. In the tirstplace we will suppose the plateau P to be down to its fullestextent inthe press bor B, as shown in fig. 5. When the plateau is in thisposition the springs B are above the fulcra u, of' the levers Y, andhave a tendency to press the liftcrs X X towards the headvotl the ram D,and the valve S is in a closed state, as the pendent wedge Z, attachedto the plateau, is between thc levers W, and when the plateau reachedits lowest point in descending, forced or spread apartsaid levers andmoved the levers V V, which in turn actuated the wedges U U, moving theminward or towards the valve stem f. so that the spring f forced thevalve S down Aupon its seat. The springs B are above the fulera u of'the levers Y, on account of the plates q having come in contact with thestops w previous to the plateau reaching `its lowest point. The doors CC are opened, the head-plate G raised to one side of the press box, andthe latter lled with the substance to be compressed; the doors beinglclosed, and the head-plate should back over the press box the doorsbeing firmly secured in a closed state by adjusting the clamp frame Dover the ends lof the battons a, and driving the key E up in the loops ee', wat-er is then forced into the pipe R by .means of the usual pumpprovided with a valve as usual, graduated to suit the pressure required,and the valve S being closed, the water passes down thc pipe H and upinto the ram D, and acts against the ram E, raising the same, andconsequently the plateau P, and packing or pressingI the substancewithin the press box. The ram E rises until the collar e or O comes incontact with the rest Q on the ram-head D, at which time thelowcr endsof the lifters are pressed over the head of the ram D by the springs B,and the pawls Y are thrown into the recesses i t' in the hcad'of the ramD, and the lower ends of the lifters in this movement strike the leversW W and actuate the levers V V, so that the latter`- will move thesliding wedges U U outward and raise the cross-head T, and thereby openthe valve S so that the water will pass down the pipe K and up imo thelower part of the cylinder C, and acting against the ram D wifi ellifters X X, acting upon the plateau D, which, under the pressure oowing to its greater area, the motion being reduced of course inproportion to the increase of power. Thus, in the first instance, theplateau acts or moves more rapidly under th pressure of ram E, owing toits small area,

f-thc ram D, acts with an' incr-eased power evate it; said ram, throughthe medium of'thcv and this is termed the packing ram, as it simplycompacts or presses the loose substance in the press box, and

prepares it to receive the increased pressure ofthe larger ram D, which,in consequence of its greater power, I I

term the compress ram. At the time the compress ram D reaches itshighest or culminating point, the springs B will be below the fulcra nof the levers Y, on account of the knobs or weights o coming in contactwith the base of the framing of the press before the plateau reaches itshighest point. The substance being thus compressed the doors C C areopened, the compressed substance bound'and removed from the press box,and the two rams allowed to descend by permitting a discharge of thewater from within cylinder C and the ram D through pipe R, and theplateau P descends, the lower ends Aof the lifters X coming in contactwith the rests j, which retains the lifters and plateau until the headof ram D descends sufficiently to allow the pau'ls Y of the lifters X tobe free from the recesses in the head of ram D, when the sprin'gs B', inconsequence ofbeing below the fulera u, as' shown in fig. 2, throw thelifters olf from the head of ram D and the plateau descends to itslowest point;- the wedge Z passing between the levers W W and actuatingthe levers V V, so that the latter will move towards each other, thesliding wedges U U, and allow the springf to close the-valve S. Theplates g g, just previous to the plateau reaching its lowest point ofdescent, come in contact with theV stops w and cause the springs B to'beadjusted above the fulcro. u of the levers Y, as shown in fig. 5, andall the parts will then be in the position described at the commencementof the operation.
